Introduction: Battery Adjustable Power Supply - Ryobi 18V
Build up a DPS5005 (or similar) into a Ryobi One+ battery powered adjustable power supply with a few electrical components and a 3D printed case.
Step 1: What You Will Need
You will need:
3D printed case. Files at: Thingiverse
Ryobi One+ battery
DPS5005 power supply or equivalent (DPS3003, DPS3005)
Combined red/black binding post
2 spring contacts
2 screws for securing the spring contacts
2 ring connectors for attaching to the spring contacts
2 ring connectors for attaching to the binding posts
18 inches of 18 gauge wire
I put a few electrical kits together if you want to buy all the small pieces in 1 package: E-bay Small components
I also have a kit with the 3D print included too incase you can't 3D print your own: E-bay Case and Small Components
Step 2: Install the Binding Posts
The stack up I used is laid out in the picture. You will want to attach the wires to the ring terminals before screwing them down.
Step 3: Install the Power Supply Into the Case
This should just be a press fit into the case. You can use a little adhesive if it won't hold on its own.
Step 4: Install Battery Terminals and Wires
This is probably the most challenging part. You need to install the 2 battery spring contacts, on top of them are 2 more ring terminal attached to wires and then screws to attach them both to the case. My battery has + and - markings on the top. I used these to get the polarity correct for the wiring.
Step 5: Connect Wires to the Power Supply.
The last steps is to attach the wires to the power supply. The wiring is pretty straight forward. The battery contacts and the input and the binding posts are the output.
Step 6: ENJOY!
